基于组合权的灰色关联分析在供电企业营销效果综合评价中的应用

在供电企业电力营销效果综合评价中,客观赋权法体现了指标的信息量,而主观赋权法体现了指标的价值量,综合评价应当体现二者的统一.针对电力营销效果评价,提出了基于组合权的灰色关联分析方法.对传统的灰色关联法进行改进,将该方法用于供电企业电力营销效果评价,得到了较好的结果.

New product development in foreign customer relationships: a study of international SMEs

Abstract

This study identifies a gap in research concerning how small and medium-sized enterprises (SMEs) can benefit from pursuing locally (rather than globally) oriented internationalization strategies. Becoming overly dependent on one single foreign market could potentially reduce the inflow and diversity of new knowledge that can serve as input for new product development. This study discusses how this risk can be minimized. In this endeavour we create a theoretical model that investigates how the local sales concentration and relationship-specific commitment of SMEs relates to new product development. To do this we draw on the behavioural internationalization process framework. The theoretical model is tested on an effective sample of 188 Swedish SMEs. The results show that relationship-specific commitment mediates the effect of local sales concentration on new product development. The implication is that investments which enable collaboration in important business relationships are crucial requisites for keeping firms innovative and in pace with market fluctuations. The findings thus contribute to international business literature by showing that a local market scope of operations combined with a relationship orientation are beneficial for new product development in international SMEs.     

大众知情权侵犯个人隐私权的成因及其制约

个人隐私权和大众知情权是一对矛盾体。媒体在新闻报道中侵犯个人隐私权的状况时有发生,但是其成因却是各种各样的。在深入讨论大众知情权对隐私权侵犯的成因后,得出公共利益、媒体利益和个人利益冲突,是造成这种现象的主要成因;并在此基础上,对如何平衡个人隐私权和大众知情权提出建设性的解决方案。     

生态文明建设下风、光发电生态效益模拟与评估——以甘肃省为例

在我国生态文明建设日益受到重视的背景下,文章对风、光发电的生态影响进行了整体、全面的研究。首先,构建了分析风电和光伏发电对生态系统影响的系统动力学(system dynamics,SD)模型,并提出一种改进的耦合协调度模型;然后,以甘肃省为例进行SD情景模拟;最后,评估了多政策情景下甘肃省生态系统耦合协调度。结果表明,风电技改增效和光伏发电技改增效更有利于整个生态系统的发展。通过理论分析论证了甘肃省现行风、光发电政策的科学性,并为进一步发展风、光发电从而促进生态文明建设提出建议。     

火电项目融资的现金流量风险评价——基于探索图的指标体系

已有关于火电项目风险的研究基本未重点考察现金流量风险。本文从火电项目融资的角度出发,发现现金流量风险的重要性,尝试性地运用复杂科学管理系统思维的工具——探索图,为火电项目的建设期、试生产期和生产运营期分别建立风险评估指标体系,并用动态模糊评价方法确定每期和全过程的现金流量风险程度,为火电项目融资决策提供依据。     

Loan price modelling for local governments using risk premium analysis

Previous studies have highlighted the question of government loan interest as one of great current importance. Government borrowing levels are high, and reducing interest payments would generate savings to meet other spending needs and/or to lower taxation, thus supporting the sustainability of public finances. However, no previous study has presented a method for a local government to calculate its own credit risk and thus be in a position to negotiate lower interest rates on its borrowing. This article defines a financial model that enables local governments to estimate the interest rate payable on a bank loan, based on their credit risk premium, in accordance with the Basel II rules and the findings of our empirical study of large local governments.     

金融发展水平对地方政府债务适度规模的影响研究

在考虑金融发展水平对地方政府债务规模影响的基础上,构建了以金融发展水平和地方政府债务规模的门槛面板模型。实证研究发现,金融发展水平对地方政府债务规模存在“门槛效应”,金融发展水平越高的地区,地方政府债务规模门槛值也较高;金融发展水平中等的地区,地方政府债务规模门槛值相对较低;而一旦地方政府规模超过最高“门槛值”,地方政府较难通过金融市场来缓解债务压力。因此,长期来看,地方政府应将债务控制在一定适度范围内,并加强债务风险管控能力。     

中国生物质发电产业发展动力因子研究

介绍了中国生物质发电产业的市场环境和政策环境。基于此,识别生物质发电产业发展的内生动力因子和外源动力因子,并利用计量经济学理论对动力因子的相关性进行分析。建立解释结构模型研究动力因子之间的关系,分析经济要素之间的作用机理。结果表明:所有的动力因子通过不同的途径和方式最终指向政策和资源禀赋因子;能源安全因子、环境保护因子、农村发展因子影响电力需求,投资影响电力供给;合理的要素成本价格需要科学的政策组合进行有效支持。     

Asymptotic analysis for optimal investment and consumption with transaction costs

We consider an agent who invests in a stock and a money market and consumes in order to maximize the utility of consumption over an infinite planning horizon in the presence of a proportional transaction cost . The utility function is of the form U(c) = c^1-p/(1-p) for p > 0, . We provide a heuristic and a rigorous derivation of the asymptotic expansion of the value function in powers of , and we also obtain asymptotic results on the boundary of the no-trade region.Received: July 2003, Mathematics Subject Classification (1991): 90A09, 60H30, 60G44JEL Classification: G13Work supported by the National Science Foundation under grants DMS-0103814 and DMS-0139911.
